The pollen grains of raspberry exhibited the average size (length x width) of x in glycerol conditions, followed by ( x µ) in water suspension. The viability of fresh pollen grains ranged from % to % in hermaphrodite or bisexual flowers. 25 % sucrose solution + % boric acid solution showed the highest pollen germination of with the maximum pollen tube length () after 48 hours interval. |
